PHOTOGRAPHIC CAMERA.

SPECIFICATION forming part of Letters Patent No. 772,285, dated October11, 1904.

Application filed any 17, 190s.

To @ZZ whom, it may concern:

Be it known that I, J AMES MILLARD, a subject of the King of GreatBritain and Ireland,

residing at Newtown, Wigan, in the county of Lancaster, England, haveinvented new and useful Improvements in Photographic Cameras, of whichthe following is a specification.

The improvements which form the subject of this invention relateprincipally to maga- Zine or hand cameras; but parts of my invention arealike applicable to Kinear, stud/io, and other cameras.

In the accompanying twoisheets of drawings illustrating my saidinvention, and to which I hereinafter refer, Figure l is a frontelevation, and Fig. 2 an elevation, of the operating side of my improvedphotographic camera. Fig. 3, Sheet 2, isY an elevation of the same sidewith the cover removed. Fig. 4 is a longitudinal section. Fig. 5 is atransverse section on line B B. Fig. 6 is an elevation with camera-front removed, showing the shutter. Fig. 7 is an end view of theshutter, showing the disengaging mechanism.

In the views the same characters refer to like parts.

According to this invention I form the back of a camera such as hereinfirst named with a rectangular chamber, as a, that may-contain one dozenor other preferred number of plates or films in sheaths. The floor LX ofthis chamber is raised above the licor of the depositorychamber Z, intowhich the sheaths, with the plates or films, are caused tofall afterapicture has been taken. This is effected by fixing on the` inner edgeof the chamber a, in which the plates or films are placed beforeexposure, a shallow ridge or ridges, as c c, projecting slightly upwardfrom the floor of said chamber, and on the inner side of or near one endof each of said ridges I t a small vertical spring, as d, .whichprojects a little above the ridges and presses against either the ridgesor the inner edge of the floor of the chamber. I lit correspondingridges e e to theund er side of the roof of this chamber and parallelwith the ridges c. I pivot a lever, as f, extending transversely fromone side to the center' of the chamber in proximity and parallel to thehereinbefore-described ridges c, and on the Serial No. 166,041. (Nomodel.)

inner end of said lever I form or [ix vertically1 a narrow plate g, thatis beveled on the inner side, so as to project into the chamber b alittle beyond the inner faces of the ridges c, and which can be raisedabove or lowered below the level of the door of the chamber a by theaction of the lever f. I pivot a corresponding lever j in like positionin the roof of the camera, said lever raising or lowering a beveledplate c. The free ends of these levers extend to one side of the cameraand .are actuated by a cam, as Z, that is moved by a handle, as Z.

Before the sheaths m, with the plates or films, are put in the chamber athe handle Z is turned down and toward the back of the camera until itmeets astop, which can be ZX, formed by the shape of the aperture in thecover t, the cam Z thereby causing the levers f and j to withdrawthe Zoand the front .sheath to be pressed closely Vby a spring, as m, againstthe ridges c and e at the top and bottom of the chamber.l When thehandle Z is turned toward the front of the camera until it is at orabout a horizontal p0- sition, the plate g raises vvthe bottom edge ofthe front sheath over the ridges c; but said sheath is prevented fromfallinginto the chamf ber by the springs (Z. By continuing the turn ofthe handle in an upward direction the plate presses the upper edge ofthe front sheath below the ridges e and the bottom edge of said sheathbetween the ridges c and springs ZZ, when it falls forward into thedepositorychamber. The handle Zl is then brought back to its originalposition, which causes the plates g and c to recede, thereby permittingthe next sheath to occupy the place from which the sheath containing theplate or film on which the picture has been taken hasby these means beenremoved.

When the handle Z is turned and releases a sheath, a catch or ratchet,as p, is caused to engage with the ratchet-teeth Q on the peverticalplates g and riphery of the dial g by said catch or ratchet p beingeither connected to the handle Zl or attached to the rod jx, that isconnected to the lever y', which is actuated by the cam Z in the mannerhereinbefore described, said dial being thereby moved forward one toothand I OV with the levers l0 and 11.

the number indicated either by a pointer or coming opposite an aperturet' in the cover t, said catch or ratchet p passing freely over theratchet-teeth q' when the handle ZT is turned back. The spring-blind 1is wound ou the spring-roller 8 simultaneously with the discharge of thesheath into the depositorycham ber Z by the cord Z, that is connected tothe Wire Z3, which when the handle Z is turned toward the front of thecamera is wound on the grooved pulley Z2. I form a shutter in which theaperture 2 in the spring-blind is caused to be covered while passing thelens when the blind is being rewound by fitting a stud or catch 3 on theblind over the aperture, said catch engaging with a catch 4 on thescreen and drawing said screen up with the blind, thereby covering theaperture in the blind until said aperture has passed the lens, when thecatch 4e on the screen is pressed orf the catch 3 on the blind by a pin6 or an equivalent iixed in the frame of the shutter and the screendrawn down and rewound on the springroller in the bottom of the shutter.

I obtain either instantaneous or prolonged exposure by means of twinlevers 10 and 11, the lever l1 arresting the blind in ,its descent whenprolonged exposure is required, so that the aperture in the blindremains for a period opposite the lens. This is effected by a stop 9,that is fixed on one end of the spindle of the top blind-roller 8,engaging successively When the blind is vcoiled onto the roller readyfor an exposure and the lever 1.1 is moved to the side of the lever 10,the stop 9 is resting against the 1ever l() and prevents the blindunrolling. When the bulb 13 is pressed, both levers are moved outward,the stop 9 is disengaged from the lever 10, passes th'rough the space12, rotates with the spring-roller, and engages with the lever l1 andremains engaged therewith, and causes the aperture in the blind toremain opposite the `lens until the pressure on the bulb is released,when the stop will pass through the space 12 and the blind close overthe lens.

When instantaneous exposure is required, the lever l1 is moved back outof the path of the stud or stop 9, as shown in Fig. 7, and the stop thenonly engages with the lever 10, which is operated in the mannerhereinbefore described.

I claim as my invention- 1. In a photographic camera, the combination ofa device for removing a plate'or a film after a picture has been takenand successively placing another plate or a iilm in position for thenext exposure'consisting of a ridge on the floor and a correspondingridge on the under side of the roof of the chamber in which the platesare placed ready for exposure, vertical springs pressing against theinner edge of the floor, a lever in proximity and parallel to said topand bottom ridges, abeveled plate on each of said levers, a cam foractuating said levers, a catch or ratchet operated by said le-' vers andengaging with ratchet-teeth on a dial,

a blind and a screen therefor, and means for lifting the blind andscreen together and placing the-blind on the top roller ready for thenext exposure at the time of changing the plate from a common operatingmeans.

2. A camera having rollers in Jfront of the lens, a blind with anaperture and a catch 3, a screen below the blind having a catch 4, meansfor moving the blind for an exposure so that the catches will engageafter said exposure and travel together upon the opposite travel of theblind, and means for disengaging the catches upon raising the blind theproper distance.

In testimony whereotl Ihave signed my name to this specification in thepresence of two subscribing witnesses.

JAMES MILLARD.
